Hey fellas, couple questions

Will a 25det box bolt onto a 25de neo motor?

getting a new clutch/fly, should i be asking for a 25det or a 25de neo clutch/fly?

is it worth replacing the throwout bearing while its out and spigot bush?

the motor is out of an auto, is their anything im missing here, needed for a manual box, besides slave?

Im needing gearbox bellhousing bolts, can anyone link me to a thread with specs or part numbers to possibly buy new?

Got my mind set on a cushion button, can anyone give anyfeed back on this type of clutch?

Cheers Matt

Sorry for noob q's.

All RB's use the same clutch/flywheel. All RB's use the same bellhousing.

Do the throwout bearing and spigot bush if it makes you feel better, not urgent unless they're f**ked.

Other things you need... Clutch lines, fork, master, pedal.... I'm assuming you probably have a previously auto engine going into a manual shell?

These are the Nissan part #'s for bolts you need, will be about $30 all up.

0112105121 You need 4

3137715U00 You need 3

3137715U01 You need 1

Haven't used a cushion button clutch so can't comment on that.

That is incorrect. The turbo Neo uses a pull type clutch whereas the non turbo Neo uses the earlier push type setup. The bell housings have the same bolt pattern but they are most definitely not the same bell housing.

However to answer this guys question, the turbo Rb25 gearbox from an R33 will bolt up and uses the same clutch as the N/A Neo.

You need to get rid of the auto spigot from the back of the crank and put in the bronze spigot for the manual instead. The tail shaft is also different so you will need the turbo shaft

Ah yeah forgot about pull/push. I know the bellhousings are different, I just meant as you said that they will all bolt up.

I'm pretty sure they are M10 x 60mm or 65mm. Measure the bell housing thickness where the bolts go through and add 15mm then add a spring washer to your bolt. That should give you 12mm of thread.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
